I haven't used a real HP-49, I had a HP-48G. It usually ran circles around the TI 85, and TI 82, and TI 92s that people had back in 1998. I've heard good things about the TI 89, but after RPN I couldn't just go back to Algebraic. I've used the HP49 emulator on my iPAQ and the thing is slow as all get out and seems like a regression compared to my HP 48. So I typically use the HP 48GX emulator on my iPAQ. Too bad the bleeps at HP didn't release the ARM builds of the Xpander software.

I used to have a TI-30 in high school. My fingers were going numb because of the stiffness opf the keys, so I poked a hole in the body and stuck there a DB-15 connector. Then I found a surplus full-size calculator keyboard, relabeled the keys, rewired the thing and attached it to the port. Given that everybody had a TI-30 at the time, mine was pretty interesting.

Why does everyone you know use TIs? They've got the education market locked up. Even down to elementary school, all the classrooms have TIs. In middle school, when the supply list gets sent home, it says "scientific calculator (TI-30 SX Hyper Alpha Turbo)" or whatever they've named their latest model. By the time the kids get to high school, TI has high name recognition -and most of the teachers there are also teaching to the TI-82/83/83+.
